European yew (Taxus baccata L.) is a key tree species in forest ecosystems, contributing to biodiversity and ecosystem stability. However, its populations have declined significantly due to historical overexploitation, habitat fragmentation, and increasing environmental pressures, particularly under ongoing climate change. This review provides a comprehensive analysis of the ecological characteristics, distribution, and silvicultural management of yew, emphasising its role in close-to-nature forest management. It discusses the species’ resilience to drought, shade tolerance and potential for adaptation to changing environmental conditions. Conservation strategies including natural and artificial regeneration, site-specific silvicultural interventions and the need for wildlife management to mitigate herbivore damage are also reviewed. The economic and pharmacological importance of yew, particularly as a source of taxanes for anticancer treatment, is also highlighted. The review also examines the sensitivity of the species to biotic and abiotic stressors and predicts its future distribution under climate change scenarios. The results highlight the need for targeted conservation measures, assisted migration, and adaptive forest management to sustain yew populations. Future research should integrate genetic diversity studies, climate modelling, and field-based silvicultural experiments to increase the species’ viability and ecological functions in European forest ecosystems.

Ponderosa pine (Pinus ponderosa) is one of the most valuable American pines growing naturally in the western and Pacific states of Arizona and California. Based on previously published research, its ecological valence makes this species suitable for introduction worldwide, including Europe. In Central Europe, climate change—the primary cause of significant dieback of native tree species, such as Norway spruce and Scots pine—has increased the need to explore new methods to ensure forest stand sustainability. Introducing previously overlooked tree species, such as ponderosa pine could help address this challenge. We reviewed 229 research sources to analyze P. ponderosa’s potential for utilization in new areas. The existing research from its native distribution range indicates ecological plasticity and strong resistance to drought and climatic extremes. Production parameters were evaluated in young European forest stands with a stand volume of 430 m3⋅ha–1 at the age of 45, pointing toward a promising use in the forestry sector. In European forestry, ponderosa pine’s importance could grow due to its adaptability to warm and dry climates and tolerance of diverse soil conditions. Moreover, the extraordinary quality and texture of the wood, as well as ponderosa’s biodiversity and ornamental functions, make the species destined to become part of future landscapes and forest ecosystems of Central Europe under changed climatic conditions. However, we also see challenges and scientific gaps associated with the management of ponderosa pine and its introduction to mixtures with native tree species without prior verification and silviculture recommendations.
